Specification of Letters Patent.

Application filed April 26, 1912. Serial No. 693,370.

. To all whom/it may concern Be it known that I, JAMES M. JOHNSON, aresident of New Brighton, in the county of Beaver and StateofPennsylvania, have invented a new and useful Improvement inCollapsible Tubes, of which the'followin is a full, clear, and exactdescription, re erence being had to the accompanying drawings, formingpart of. this specification, in which- Figure 1 is a perspective view ofa tube with one form of my improved device attached. Fig. 2 is asectional view on the line IIII,showing the device in its open position,andFig. 3 is .asimilar View showing the device closed.

My inventionrelates to the class of collapsible tubes for feedingviscous o1 pasty materials by compressing the body of the tubes.'Heretofore openings in the nozzles or necks of tubes have been closedby means of collars or caps, which were provided with openings whichwere brought into register with the openings in the nozzles or neckswhen it was desired to eject some of the material from the tube.Closures of this character have numerous disadvantages, as the collarsor sleeves are very liable to be so tight that it is almost impossibleto rotate them in order to bring the openings in register with eachother, or that they rotate so freely that the opening through the nozzlewill not be sealed, thereby leaving the contents of the tube at theopening exposed to the action of the atmosphere. Another greatdisadvantage arose from the fact that the opening through the collar orring was always filled with material which was left from the last timethe device Was used and which could not be removed from said openingexcepting by the use of a sharp instrument which would be adaptable toscrape the paste out of the opening.

One of the objects of my invention is to provide a sealing device whichcan readily be rotated about the neck of the-nozzle, and which willalways seal the opening when the device is in sealing position.

A further object of my invention is to provide a device of thischaracter from which all of the ejected material can readily be wipedfrom the neck of the nozzle and thereby provide a sanitarydevice.

The precise nature of my invention will be best understood by referenceto the accompanying drawings, which will now be appended claims.

In the draWings,-the numeral 2 designates the body of the tube which maybe of any well known construction, and which is provided with a neck ornozzle at its upper end.

This neck or nozzle is provided with a head 4 around the upper edgethereof and a bead 5 at its lower portion, and 6 is a groove between theheads 4 and 5.

7 designates a vertical head or stop which I have shown as extendingfrom the bead 4 to the head 5. Rot-atably mounted. between the heads 4and 5 is a spring clip 8 having a handle 9 which is formed by bendingthe body of the material upon itself. This clip is also provided with arecess 10 in which is seated a pliable sealing pad 11 of cork or anyother well known material which is adapted for sealing an opening. Ascan be seen by reference to the accompanying drawings, the clip 8extends from the head 4 to the bead 5 and surrounds a little more thanone-half of the neck or nozzle of the tube.

12 designates a longitudinal opening through the side of the nozzlewhich is arranged to be closed by means of the clip 8 when it is movedinto the position shown in Fig. 2, and-which is opened to permit thematerial to be ejected when moved into the position shown in Fig. 3. Thevertical rib 7 is arranged to provide a sto for miliar with the art thatthe clip member w may have various shaped handles, and may be applied inany manner, and also that the stop may be varied inmany ways.

The advantages of my invention result from theprovision of a closure foraside opening of a nozzle which is arranged to be held in properposition in relationto the nozzle by means of the spring action of theclip. In-this connection, it is desired to call attention to thepeculiarly 'efi'ective action of said clip." The handle portion 9, beinglooped, as shown,,'constitutes, in effeet, a spring member, and as itextends to one side of the neck or nozzle, itprovides comparatively longside arms. Consequently, the portions of these arms that em brace orclasp the neck or nozzle, have a comparatively long radius of action, orin other words, the axis on which they may be said to swing toward eachother, is located at adistance from one side of the neck or nozzle. Theresult is important, inasmuch as the entire inner surfaces of theneck-engaging portions are thus yieldingly pressed against the neck ornozzle, and the pressure of the packing is evenly distributed over itsentiresurface.

I claim:

1. A receptacle having a nozzle portion provided with a lateraldischarge opening, and a closure for said opening comprising a cliprotatably mounted on the nozzle and having op osite side portions spacedapart and -,exten ing around a portion only of the nozzle portion, saidclip having a portion between its ends bentoutwardly to form a springmember that yieldingly holds the said side portions with a distributedeven pressure against the nozzle portion, and said spring member alsoacting as a handle for the closure.

2. A receptacle having a nozzle formed with a lateral discharge openinand a (:10-

sure for said opening, said c osure comprising a clip or sleeve memberrotatably mounted on the nozzle and embracing a portion thereof, one endportion of said member being outwardly ofi'set at its free end portionto form a recess, and a sealing pad seated in said recess, the centralportion of said member being bent to form a spring loop which alsoserves as a handle for the closure.

In testimony whereof, I have hereunto set my hand.

JAMES M. JOHNSON.
